Emerging evidence for the early introduction of allergenic foods for the prevention of food allergies, such as peanut allergy in Western populations, has led to the recent publication of guidelines in the US and Europe recommending early peanut introduction for high-risk infants with severe eczema or egg allergy. Peanut allergy is, however, much less prevalent in Asia compared to the West. Varying patterns of food allergy are seen even within Asian countries - such as a predominance of wheat allergy in Japan and Thailand and shellfish allergy in Singapore and the Philippines. Customs and traditions, such as diet and infant feeding practices, also differ between Asian populations. Hence, there are unique challenges in adapting guidelines on early allergenic food introduction to the Asian setting. In this paper, we review the evidence and discuss the possible approaches to guide the timely introduction of allergenic food in high-risk infants in Asia. This article is protected by copyright.

Loss of immunosurveillance is a major cause of cancer progression. Here, we demonstrate that gelsolin, a constituent of ejaculate, induces apoptosis of activated lymphocytes in prostate cancer. Gelsolin was highly expressed in prostate cancer cells, and was associated with tumor progression, recurrence, metastasis, and poor prognosis. In vitro, secreted gelsolin inactivated CD4(+) T cells by binding to CD37, and induced apoptosis of activated CD8(+) T lymphocytes by binding to Fas ligand during cell contact dependent on major histocompatibility complex I. Moreover, secreted gelsolin bound to sortilin, which in turn bound to Wiskott-Aldrich syndrome protein family member 3, thereby enhancing the endocytosis and intracellular transport of essential lipids needed to facilitate tumor growth and expansion. Under normal conditions, gelsolin is a seemingly harmless protein that prevents immune responses in female recipients. In disease states, however, this protein can inhibit immunosurveillance and promote cancer progression.
Multidrug resistance is one major barrier to successful chemotherapy. Although several studies have attempted to overcome resistance of cancer cells to anti-cancer drugs, key determinants of resistance remain largely unknown. The objective of this study was to investigate whether microRNAs might play a role in the acquisition of resistance. Human colorectal cancer HCT-116 cell lines were transduced with a lentivirus library containing 578 precursor microRNAs (miRNAs) to establish cell lines resistant to 5-fluorouracil (5-FU). Specific miRNAs were identified from four different resistant clones and a miR-195-expressing resistant clone (HCT-116_lenti-miR-195) was further investigated. The HCT-116_lenti-miR-195 cells showed resistant phenotype. These cells grew faster after 5-FU treatment compared to control cells (HCT-116_lenti-control). Check point kinase 1 (CHK1) and G2 check point kinase WEE1 were found to be direct targets of miR-195. Downregulation of miR-195 sensitized HCT-116 cells after 5-FU treatment. Our results demonstrate that miR-195 can promote acquisition of drug resistance to 5-FU.
Food allergy results from a loss of oral tolerance toward ingested antigens. Oral immunotherapy is thought to initiate desensitization through interaction of an allergen with mucosal dendritic cells that initiate downstream immune system modulation through regulatory T cells and effector T cells Keyword: CD4(+) T cells.

Volumes are however small or highly diluted through reflex tearing AbstractText: Secretions reflect the local inflammatory activity and provide valuable information about the immunological reaction to allergens at the target organ. There is increasing evidence of the potential clinical role of their analysis, for diagnosis, and monitoring of allergic rhino-conjunctivitis.
AbstractText: Alarm fatigue is a widely recognized safety and quality problem where exposure to high rates of clinical alarms results in desensitization leading to dismissal of or slowed response to alarms. Nonactionable alarms are thought to be especially problematic. Despite these concerns, the number of clinical alarm signals has been increasing as an everincreasing number of medical technologies are added ...

Although oral immunotherapy (OIT) is effective at inducing desensitization, the temporary nature of this effect and high rates of adverse reactions have highlighted a need for novel strategies to improve tolerance induction and safety. One such strategy is the use of an adjuvant together with food immunotherapy to either suppress allergic reactions and/or modulate the underlying allergic immune response.

... in the transition from acute to chronic pain and for diagnosis and development of optimal management strategies. The neuroplastic processes may result in gain (sensitisation) or loss (desensitisation) of function in relation to the incoming nociceptive signals. Such processes play important roles in chronic pain, and although the clinical manifestations differ across condition processes, they share some common mechanistic features.
Molecular modeling and simulation experiments provide insight into oxytocin-TRPV1 interactions, which resemble DkTx. Together, our findings suggest the existence of endogenous regulatory pathways that modulate nociception via direct action of oxytocin on TRPV1, implying its analgesic effect via channel desensitization Keyword: MD simulations. Keyword: TRPV1 ion channel. Keyword: molecular dynamics simulations.
... tool in evaluating HSRs to biologics; however, its predictive value depends on the type of reaction and the monoclonal antibody. Desensitization is a new approach to safely reintroduce biologics when they are first-line therapies, and it is available for immediate and delayed reactions. Research is needed to further understand the mechanisms of reactions to monoclonal antibodies and their management.
Abstract: The endeavor to study desensitization in kidney transplantation hasn't been matched by an effort to investigate strategies to prevent sensitization. In this study (NCT02437422), we investigated the safety, impact on sensitization and pharmacokinetics of SANGUINATE (SG), a hemoglobin-based oxygen carrier, as a potential alternative to packed red blood cells (PRBC) in transplant candidates with end-stage renal disease ...
The most common override reasons in the inpatient and outpatient settings were 'administer per desensitization protocol' (n = 64, 31.7%) and 'patient does not have this allergy' (n = 7, 63.6%), respectively. No harm was associated with overrides in either setting, particularly because many medications were not administered AbstractText: Overrides of 'definite' anaphylaxis DAI alerts were common and often appropriate.

Methylation by protein arginine methyl transferase 1 (PRMT1) desensitizes the mitochondrial Ca(2+) uptake machinery and reduces mitochondrial Ca(2+) accumulation in cancer cells. In case of PRMT1-driven methylation, proper mitochondrial Ca(2+) uptake is reestablished by increased activity of uncoupling protein 2 (UCP2), pointing to an importance of these proteins for cancer cell survival and activity.
This decrease was associated with the AMPT-induced reduction of monetary earning in HC in contrast to rBN participants.

The vast majority of laboratory-based experimental studies have revealed that violent media exposure causes increased aggressive thoughts, angry feelings, physiologic arousal, hostile appraisals, aggressive behavior, and desensitization to violence and decreases prosocial behavior (eg, helping others) and empathy. Still, to more fully understand the potential for long-term harm from media violence exposure, the field is greatly in need ...
